PLOW.

' Application'filed February lS. 1927; Serial No. 169,428.

The, invention relates toimprovements in plow bottoms and particularlytomeans for.

connecting a sheet metal frog with a detach-j able share. r t

The principle object of the invention is to substitute a pressed steelfrog structure for the castor malleable frogs heretofore inuse and tosimplify the structure thru which the share- -is detachably interfittedwith and;

plowbody.--

locked to the frog and other parts "of the A further; object is provideassembling meanscomprising a ;minimum number of loose partsand havingits share locking mean so organized asto hold the share in positionbymeansofbut' one tension element engaging an integral abutment 101111116frog.

The invention, therefore; :resides' in the improved. features ofconstruction hereinafter set forth *and particularly defined in:

ing the moldboard and landside, and handles 15 connected to' themoldboard andbeam; respectively. A heel piece 16 is preferably .securedto the end of the landside. With the exception of the frog, theseopartsare of conventional construction, The moldboard 11 is connected tothefrog by one or more bolts 17, andthe landside 13. is also rigidly"connected to the frog as by bolts 18 and for purposes of thisdisclosure these parts are 1 regarded as permanently connected@ Thedetachable share 12 is provided with a land side flange or gunnel 19,which forms a continuationiof the landside 13 and formed with'the usualcutting edge which oins the moldboard on the line 20 in the usual maniner. The frog consists of a sheet metal plate bent to provide angularlyrelated portions 21, 22 engagingthe, landside' and mold: board,respectively,'and which extend forf wardly beyond thesame to form atoepor- "tion 23 similarly engaging .theshare.

V The landside flange of the share is provided with an inwardlyprojecting stud 24 whichextends beneath the 'end ofithe toe 23 of thefrog whichis cut away to form a seat .25 which engages the stud 24 whenthe parts are assembled. The part'of the frog engaging the under side ofthe moldboard and.

share is formed with free parallel edges 26,

27 connected bya right angular;-edge;28

forming a beveled shoulder 29 connecting the two parallel edges.

At the reanthe edge is 26, terminates in an upstanding lug great-3O.

stuck up "from the metal ofthe frog and pro- 1 vided with an aperture orbolt opening 31 for a purpose to be described. I Thesho'ulder i :29 isso located as to bridge or intersect the E junction line between themoldbo'ard' andi.

share when the parts are assembled. 1

It will be noted that the edge 2610f ale frog is substantially parallelwith the-free. w

edge ofthemoldboard'and that theear 30. is parallel and co-extensivewiththe shoulder edge 29.; The, share hasion it astud 32 which, H ispreferably formed with a laterall 'BX-q tendingfianged head to provideahoo -lik'e' abutment. This stud is 'so'positioned that.

it will liein the angleibetwe'en the. edges of; the frog and directlyopposite the. shoulder.

vided a tehsionbolt: 33 provided iwith afl 29 when the parts :areassembled. For con- 'nectin'g the share and ifrog; and-drawing; up. utheparts'rintb fixed relation, there isnpros 1;;

flattened offset head. 34 having an opening which is adapted to passover the head of the stud 32. The head of the bolt bears on the beveledshoulder 29, and its screw-threaded end passes thru the aperture 31 inthe ear 30. The nut 35 bears against the outer side of the ear andserves to draw up the bolt to lock the share to the other parts of theplow body, the head of the bolt engaging the shoulder 29 to assist thisaction. Preferably a clip 36 is secured to the under side of theshare'to overlap the underside of the moldboard andto assist inretaining the sharein position. The rear end of the frog may be formedwith. a raised seat 37 for reception of the plow beam. V i V It will beclear from the above description that a simple interlocking structurefordetachable shares-has been devised, characterized by the use of apressed steel frog so re-' latedto the moldboard and share as to bringthe locking element in position to apply ten-. sion ina directionparallel to the moldboard edge and'bringingthe share firmly and securelyin positionagainst the moldboard,

landside, and frog, and usingbut one loose element, the bolt 33, in itsconstruction, which bolt is so located as to be conveniently accessible.

The above disclosure exemplifies but one preferred form of theinvention, which may be varied within the scope of the following claims.

What is claimed as new is:

1. The combination with a plow body comprising a moldboard, landside. asheet metal frog permanently connecting said parts and a detachableshare interfitting with the moldboard, landside and frog; of means forlocking the share in position com prising a stud on the share, anupright ear struck up from the metal of the frog at the moldboard edgethereof, and a locking element connecting said stud and ear.

2. The combination with a plow body comprising a moldboard, landside. afrog permanently connecting said parts and a de tachable shareinterfitting with the moldlooarol, landside and frog": of means forlocking the share in position comprising a laterally extending shouldertermed on the middle portion of the frog, an integral apertured lug onthe frog in alignment with said shoulder, a stud on the share adjacentsaid shoulder, and a locking bolt received in the apertured hu andhaving a head en gaging the stud. i

The combination with a plow body comprising a Inoldboard, landside, afrog permanently connecting said parts and a de tachable shareinterfitting with the moldboard, landside and frog; of means forlocking; the share in position comprising a laterally extending shoulderformed on the middle portion of the frog the edge of which intersectsthe junction line between the share and moldboard, a stud on the shareopposite said edge of the shoulder, an integral lug formed on the frogparallel with said edge of the shoulder, and a fastening bolt connectingthe stud and lug and formed with a part hearing on said shoulder.

4.. In a plow body assembly the combination with the lllOlCllJOflltl,landside and share, of a sheet metal frog holding said parts inassembled relation and bolted to the nioldboard and landside, theportion of said trogengaging the moldboard having a free loiuritudinaledge terminating at the rear in an upstanding ear struck up from themetal of the frog, and releasable inter locking connections between thefrog and share including a stud on the share and a tension boltconnecting the stud with the car on the frog.

5. In a plow body assembly, the combination with the moldboard, landsideand share, oil a sheet metal frog holding said parts in assembledrelation and bolted to said frog: engaging the under sides of themoldboard and share being formed with parallel l'ree longitudinaledgesconnected JOHN I SHEAHAN.
